Help with metasploit framework 3.1

["Mau Bs" <drm.mailist () gmail com>]

Hello everyone, I'm new to all this security area, but trying to learn
a few things by myself. This is my very first post in the mailing
list. I was trying to install the Metasploit Framework 3.1 for Windows
(not the Cygwin one), and the installation goes ok, but, when I try to
execute the GUI interface, it prompts an error that says it can not
find the entry point for XML .. function located in xmlparse.dll. I
began tracking the problem along the ruby scripts, and what I found is
that when it tries to execute "require pango.so" in the pango.rb file,
it fails. Got any clues?
Thank you!
